1. An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive a configuration that indicates a set of frequency components corresponding to a plurality of quasi co-location (QCL) mappings, the configuration indicating multiple sets of reference signals,
wherein the configuration associates each set of reference signals, of the multiple sets of reference signals, to different subsets of frequency components included in the set of frequency components, and
wherein the plurality of QCL mappings includes:
a first QCL mapping between a first set of reference signals, of the multiple sets of reference signals, and a first subset of frequency components, of the set of frequency components,
a second QCL mapping between a second set of reference signals, of the multiple sets of reference signals, and a second subset of frequency components, of the set of frequency components, and
a third QCL mapping between a third set of reference signals, of the multiple sets of reference signals, and at least one of the first subset of frequency components or the second subset of frequency components; and
monitor for one or more reference signals, corresponding to the set of frequency components, based at least in part on the configuration.
